gln_check_backend_operation_support

Declared in <galanthus/c_api/gln_capi.h>.

GLN_API int GLN_CALL gln_check_backend_operation_support(
    gln_backend_t*          in_backend,
    gln_backend_operation_t in_operation);

Family: Backend capability helpers
Return type: int

Purpose

Reports whether an opened backend supports one backend operation enum value.

Return

Returns 1 when the backend kind supports in_operation; returns 0 otherwise.

`int`	value	value

Parameters

Name	Direction	Type	Nullability	Ownership
`in_backend`	input	`gln_backend_t*`	nullable	borrowed
`in_operation`	input	`gln_backend_operation_t`	value	value

Capability Scope

These helpers expose static C API operation/backend-kind support from the operation table declared in operation_descriptor.hpp.

They do not check live bank entitlements, account product availability, user permissions, bank parameter data for a specific session, or whether a particular request will succeed.

When a statically supported operation is rejected by the provider or an account product is unavailable, the operation reports that through the gln_backend_result_t envelope outcome, status, and error details.

Return Convention

The function returns 1 when the backend kind supports in_operation and 0 otherwise.

A NULL backend returns 0. GLN_BACKEND_OPERATION_UNKNOWN and enum values outside the operation table also return 0.

Operation Mapping

Support is keyed by gln_backend_operation_t. Use gln_get_backend_operation_name and gln_parse_backend_operation_name when converting between enum values and stable operation-name strings.
